Abstract
The spectrum of depolarized light scattered from monatomic fluids has been measured as a function of temperature and density over a range extending from the dilute-gas limit to densities as much as 50% above the normal liquid density. The low-density spectra exhibit the nearly exponential character reported earlier. Above ∼ 200 amagats the spectra broaden at progressively higher density and exhibit qualitative changes at extremely high densities. Additional spectral-shape changes occur for very high effective temperatures.
